• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

scanning 28.000 to 54.000 Modulation

When scanning between 28.000 and 54.000 which FM modutaiton is best? Regular FM or narrow?

I normally keep my scanner on auto modutaiton when scanning, but was curious if just setting one or the other would have any affect on my reception?

Amateur radio uses 28-30MHz, for the most part, so you'll find FM, AM, SSB, etc.
From 30-50MHz, most of what you are going to run across is going to be FM. FM wide, or normal, depending on your scanner. In the USA, the FCC never required stations in that segment of the band to go narrow.
Between 50-54MHz, it's the 6 meter amateur band, AM, FM, SSB, etc.

For the amateur bands, you can look at on line band plans. Those are a gentleman's agreement, but for the most part, amateurs tend to follow it.
